Volcano Watch: Kilauea’s other rift zone; young activity in the Southwest Rift Zone

  • D. DOWNS/Hawaiian Volcano Observatory geologist View looking southwest along the Southwest Rift Zone of Kilauea Volcano on Oct. 22, 2020. The unvegetated nature of the Southwest Rift Zone is on full display with the Keanakako‘i Tephra in the foreground overlying lava flows from Cone Peak (the cone in the middle ground to the right). In the distant background are the cones of Pu‘ukoaʻe (left of center) and the Kamakai‘a Hills (three hills in center).

It is no secret that the Island of Hawaii is home to fantastic volcanic features, many of which have been created during eruptions of Kilauea, Mauna Loa and Hualalai since 1800.
